GlowShift’s Blue Digital Series 60PSI Boost Gauge is essential for any diesel truck that runs high boost pressure, and ensures your turbo is performing at optimum levels and does not over boost causing critical engine damage. GlowShift’s 2 1/16th Inch (52mm) Blue Digital 60 Boost Gauge reads from 0 to 60PSI, and includes ultra-high performance features like an easy to read blue LED digital readout, a self-calibration mode at startup, a sleek ultra-thin design, as well as a low profile tinted lens. The blue digital LED readout is easily viewed regardless of the gauge angle or lighting conditions and the included 1 /8th NPT electronic boost pressure sensor is installed directly to your intake manifold for incredibly accurate readings. For easier night driving this blue digital transmission temperature gauge’s LED display will dim 30% when connected to a positive 12 volt headlight source.
